WebTypes of genetic mutations include: Germline mutation: A change in a gene that occurs in a parent’s reproductive cells (egg or sperm) that affects the genetic makeup of their child (hereditary). Somatic mutation: A change in a gene that occurs after conception in the developing embryo that may become a baby. WebIt should be noted that mutation is the ultimate source of genetic variation in all populations—new alleles, and, therefore, new genetic variations arise through mutation. * Genetic Drift. Another way the frequencies of certain genes can change is genetic drift (Figure 1), which is simply the effect of chance. list of aaman brothers albumsWebTo be more exact, genetic drift is change due to "sampling error" in selecting the alleles for the next generation from the gene pool of the current generation.

WebA gene mutation occurs when the nucleotide sequence of the DNA is altered and a new sequence is passed on to the offspring. The change may be either a substitution of one or a few nucleotides for others or an insertion or deletion of one or a few pairs of nucleotides.
